Serpent 120157 48P 19T Aluminum Pinion Gear - Precision Component  [SER120157]

High precision Serpent 120157 pinion gear

The Serpent 120157 is a precision 48P 19T aluminum pinion designed for 1/10 scale RC models. Its machined tooth profile gives reliable engagement and steady performance across varied driving conditions.

Aluminum advantages for RC gears

Aluminum pinions lower rotational inertia which can sharpen throttle response and reduce drivetrain stress. The hard anodized finish on the Serpent 120157 improves surface hardness and helps delay wear.

Notes on compatibility and setup

This 48P 19-tooth pinion fits many common 1/10 spur gears, but always confirm pitch and shaft fitment. Proper mesh adjustment is essential to avoid premature wear and to get the smoothest running feel.
